Constant-current wall warts streamline LED driver design for lamps, cabinet lights
Consider the lowly wall wart power adapter. It finds use in millions of electronics devices as a cost- and power-efficient ac-dc voltage-regulated power supply. In effect, designers of electronics have outsourced their product’s ac-dc conversion, voltage regulation, and regulatory compliance to the wall wart. It’s a cost-effective solution for most low-wattage power supply challenges ... More

Modeling in layers results in increased productivity
Productivity is related to the way in which we can model something and reliably go from that model to an implementation that meets all of the design goals. In the digital world, we have managed to incrementally increase productivity over time by raising the abstraction, improving the quality of the tools and removing tasks that previously had to be performed manually. Examples of the former are th ... More
About this blog
Brian Bailey explores how IC design teams work: the struggle for power efficiency and performance, wrestling with semiconductor processes and design methodologies, the challenges of global design teams. How do we somehow herd architecture, IP, design and verification into a successful tape-out?
The system retrofit: Thanks, iFixit!
As mentioned in my prior post, I plan to leverage iFixit’s maintenance resources (documentation and video) whenever my girlfriend’s iPhone 3GS’s embedded battery becomes sufficiently capacity-hampered to require a swap. And I’ll drop $20 on the replacement battery and tools from iFixit, even though the collection is available for less on Ebay, to acknowledge iFixit for ... More

A window into the frequency domain
From guest blogger Gina Bonini: For a recent project, I had to blow the dust off the front cover of my Discrete Fourier Transform (DFT) book from college. I actually have a few DFT books, acquired throughout my career from a variety of sources. Each one of these books is relatively thin but packed with equations and higher-order math, which makes cracking the cover and trying to “remember&# ... More

Star Wars Day: May the 4th be with you
35 years ago in a galaxy far, far away, Star Wars was about to hit theaters on May 25, 1977… Fast forward and fans have unofficially dubbed May 4 as Star Wars Day, terming “May the 4th be with you” as its slogan and coming together to celebrate the series. While I can’t claim to be a diehard fan, I have to admit Star Wars was one of the first movies to get me excited ab ... More

Researchers take spintronics for a ride
In early May, researchers at Ohio State University combined traditional inorganic semiconductors with organic spintronics, in a device that they claimed to be the first of its kind. With the prototype, the researchers managed to incorporate an organic polymer into a GaA-based device. This was no easy task, in fact according to Dr Ezekiel Johnston-Halperin, leader of the Ohio State team, ... More

Stratix Strategy for Fifth Generation
Given Altera Corp.’s earlier statements regarding 28-nm processes and HardCopy architectures, the capabilities of Stratix V were known long before the April 19 launch of the family. Still, the justification for the 28-Gbit/sec transceivers and 1.6-Tbit/sec aggregate switching capability aims for a core transport application space that may be only a partial realization of the inherent d ...

Robust Design: Patch-It Principle
The software patch is a much maligned technique for keeping systems robust because many users perceive that the majority of these patches as merely fixes of feature bugs that the developers should have taken care of before shipping the software. While there are many examples where this sentiment has a strong ring of truth to it, the patch-it principle is a critical approach to maintaining robust s ... More

Using eight bits to save two bits
Do some inflection points make as much sound as one hand clapping? It seems that way. Why else would so many device manufacturers still use 8- or 16-bit processors, when modern 32- and 64-bit processors blow those parts out of the water? The answer, of course, is cost. 8-bitters are cheap. Unfortunately, this cost-saving measure comes at a, well, cost — lost productivity. Engineering time i ... More

OLED Sony TV shines at CES from afar
I didn’t attend the CES show. This is the second straight year that start-of-the-year management tasks have kept me from the show. In this case, however, I didn’t miss much from most accounts.
